[Glycoproteins from the African swine fever virus].

The composition of African swine fever virus (ASFV) glycoproteins was studied. Isolate-specific major gp 110-140 was identified by radioimmunoprecipitation in lysate of porcine bone marrow cells infected with hemadsorbing virus strains. Carbohydrates constitute about 50% of the total mass of gp 110-140. A quantitative method is proposed for identification of the serologic relationships between ASFV hemadsorbing strains. A possible role of ASFV glycoprotein carbohydrates in the hemadsorption, virulence, and immunogenicity is discussed.
